## Abstract

A method for texturizing a workpiece uses a die assembly installed within a press having a press ram. The method includes (a) delivering the workpiece onto a center die plate; (b) forcing the press ram against an upper die plate mounted above the center die plate to descend a first contact surface associated with the upper die plate and a plurality of blades mounted to the upper die plate toward the center die plate; (c) actuating horizontal movement of the blades; (d) driving the blades down into the workpiece; and (e) contacting the first contact surface to a second contact surface associated with the center die plate to descend the center die plate in unison with the upper die plate.

## Claims

### Claim 1

A method for texturizing a workpiece using a die assembly installed within a press having a press ram, the method comprising:
a) delivering the workpiece onto a centre die plate;
b) forcing the press ram against an upper die plate mounted above the centre die plate to descend a first contact surface associated with the upper die plate and a plurality of blades mounted to the upper die plate toward the centre die plate;
c) actuating horizontal movement of the blades;
d) driving the blades down into the workpiece; and
e) directly contacting the first contact surface to a second contact surface associated with the centre die plate to descend the centre die plate in unison with the upper die plate.

### Claim 2 (depends on 1)

The method of claim 1, wherein step (e) occurs after step (d).

### Claim 3 (depends on 1)

The method of claim 1, wherein step (d) occurs after step (c).

### Claim 4 (depends on 1)

The method of claim 1 further comprising, prior to step (b), descending the press ram onto the upper die plate.

### Claim 5 (depends on 1)

The method of claim 1 further comprising, after step (e), forcing horizontal movement of the blades across the workpiece to texturize the workpiece as the upper die plate and the centre die plate descend in unison.

### Claim 6 (depends on 5)

The method of claim 5, wherein the blades are vertically fixed relative to the workpiece as the upper die plate and the centre die plate descend in unison.
